InMotion WS9569S Wheel Seal - Rear

Wheel Seal for Differential Pinion Applications

The InMotion WS9569S wheel seal is built with nitrile material to create a secure sealing surface around the differential pinion area. With a 1.365 inside diameter, 2.264 outside diameter, and 0.435 width, it is sized for precise sealing performance in rear axle applications across select Ford, Mercury, and Lincoln vehicles.

Key Features

• Nitrile construction for dependable sealing performance
• Inside diameter: 1.365 in; shaft diameter: 1.365 in
• Outside diameter: 2.264 in; housing bore: 2.259 in
• Width: 0.435 in for a compact seal profile
• Helps block contaminants, moisture, and debris from internal differential components
• Part number WS9569S for accurate ordering and fitment lookup

Detailed Description

InMotion WS9569S is a precision-engineered wheel seal for rear differential pinion sealing applications. The nitrile sealing material is selected for reliable contact and resistance to contamination, helping maintain a tight barrier where the pinion enters the differential housing. This matters in vehicles such as the Ford Mustang, Mercury Cougar, and Mercury Montego, where rear axle sealing integrity is important for long-term driveline protection. The WS9569S dimensions are matched to the shaft and housing bore requirements listed above, supporting a proper seal interface in compatible rear axle assemblies.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes and Tips

Verify the shaft diameter, housing bore, and ring gear specification before installation. Clean the sealing surface thoroughly and inspect the pinion area for wear, scoring, or contamination that could affect seal life. For best results, install the seal squarely to avoid distortion and ensure even contact around the differential pinion.

Quality Assurance

InMotion manufactures this seal with precision-focused dimensions and high-quality nitrile material to support consistent sealing performance in rear differential applications. Confirm fitment against the vehicle’s axle and ring gear configuration before ordering, especially on Ford Mustang, Mercury Cougar, and Mercury Montego rear axle setups.
